Specification of Letters Patent. Patented N 13,'1917 Application filedJaniiary 14, 1913. I Serial No. 742,007.

To all whom it may. concern:

Be it known that we, THEODORE H. Dnssnz and Gos'ravn It. 'THoMrsoN',both of New York city, New York, haveinvented certain new and usefulImprovements in Vises, of which thefollowing is a specification.

The invention relates to vises orthe like, and especially to pipe-Visesor clamps, and aims to provide improvements therein.

Means are provided by the invention whereby objects and more especiallypipes or other rounded objects, may be quickly and readily gripped'andheld, the means being adapted to operate with rapidity to adjust itselfto and to grip and securely hold the object to be held. The meansarefurther more of extreme simplicity and may be very cheaply manufactured.Other features of improvement will be set forth hereinafter.

Two embodiments of the invention are illustrated in the accompanyingdrawing, wherein Figure l is a side elevation, with parts in' section,of a vise embodying the invention.

Fig. 2 is a front view of the construction shown in Fig. 1.

Fig. 3 is a detail View of one of the parts.

Fig. 4 is a side view of a part of a vise showing another embodiment ofthe 1nvention.

Fig. 5 is a front elevation of the part shown in Fig. 4.

In said drawings, the letter A designates a bar or standard having a jawB thereon, and the letter C designates a socket-piece having a socket Dtherein for the standard, and having a jaw E, the two jaws being adaptedto grip between them articles which are to be held by the vise.

The socket-piece and standard or bar are adapted to move freely upon oneanother in order to bring the jaws together upon an object to beclamped, and are adapted to be held in clamping position by a suitablecam F. The cam is preferably adapted to bear directly upon the bar orstandard A and preferably turns in a direction to force the jaws on thestandard and socket-piece together upon an object to be held between thejaws. Either the cam or the standard may be roughened in order that thecam may exert a greater force in drawing the jaws of the vise together.In the drawing the cam is shown as roughened at G.

The inner rear face H of the socket-piece jaw will move little, if any,line,

as the movement around the edge K is on a long radius and atsubstantiallyright angles to the direction of movement of the parts. a r

The standard is preferably arranged so as to stand vertically andthesocket-piece is preferably adapted to move on the standard, oneof theparts, as in the present instance the standard, being, provided withsuitable means, such as bolt-holes L, by

which the vise maybe secured toa support. The socket-piece being movablein a vertical plane, may move under the force of gravity, when not heldby the cam, to bringthe aws together on the article tobe gripped. Thesocket-piece may therefore be raised and dropped, and be thereby broughtreadily and quickly into position to grip articles between the jaws ofthe vise. After the jaws are in position, a simple pull upon the handleof the cam will force the jaws together upon the object between them andsecurely fasten the socket-piece to the standard and hold the jaws inclamping position.

By weighting the end of the handle attached to the cam, as indicated atU the cam may be caused to operate automatically to force the jawstogether and to bind the socket-piece upon the standard.

As shown in Figs. 1, 2 and 3, the cam is provided with trunnions M, M.The trunnions M, M, are slightly larger than the cam, shoulders I N,being formed between the cam and trunnions. The hole O in thesocket-piece within which the cam and trun nions fit is bored so as tobring the shoulders N, N, between the cam and trunnions, behind thesides of the standard when the socket-piece is in place thereon, andthereby lock the cam against lateral displacement in its bearings.

In Figs. l and 5, the cam is shown as pivoted upon a pivotpin S betweentwo side plates T, T, formed on the socket-piece. In this constructionthe cam and its pivot pin may be made in separate parts, for economy inmanufacture.

The invention has been shown as embodied in a pipe vise. For thispurpose the out of a straight jaws are provided with angular grippingfaces P, P, provided with teeth Q, Q, and the jaws may be arranged tooverlap, as indicated in Fig. 2, so as to adapt the vise to operate upona greater range of diameters of pipe.

By the present invention the vise may be made of a very few simpleparts, and can be operated very expeditiously. The tightening of thejaws on the object to be gripped and the fastening of the jaws inbinding engagement may be quickly done at one very simple manualoperation. This operation may, in fact, even take place automatically.

The inventive ideas herein set forth may be embodied in otherconstructions than those herein illustrated and described. They arecapable of receiving a variety of mechanical expressions.

WVhat is claimed is:

1. A vise or the like comprising a base provided with agripping jaw andan upright bar having a plain surface; a complemental jaw movablymounted on said bar, and a cam journaled on the movable jaw androtatable into and out of engagement with said plain surface on an axisparallel thereto, to force said jaw into gripping relation both with thesaid bar and the work held between the jaws.

2, A vise or the like comprising a standard or bar and a socket-piecehaving jaws thereon, said socket-piece and bar being relatively movableto bring said jaws together on an article to be gripped, and a camadapted to fasten said socket-piece and which said jaw is adapted torock toward said first-named jaw, said jaw having an inclined face Hpermitting said rocking movement, and a cam on said jaw diagonallyopposite said bearing edge K, adapted to rock said jaw and lock it ingripping position.

In testimony whereof we have hereunto signed our names in the presenceof two subscribing witnesses.
